The script just embeds the sound in the page so that when you open the image it will play the sound simultaneously. The file hosted on 4chan's server is just a standard webm with no sound since 4chan doesn't support them.
If you want to download the video and store it with sound on your own pc you can really do two different things.
1. Save the video, copy the part after %2F in the filename and paste it after the slash in "files.catbox.moe/" into your address bar to download the sound. Then just name the files the same thing in the same folder and when you open it in your video player it should automatically dub the video with the sound (or you can just manually select it I guess)
2. Do the same as above to get the video and sound. Use ffmpeg to merge the video and audio together with the following command: "ffmpeg -i "(insert path to video)" -i "(insert path to audio)" output.mp4"
ffmpeg is pretty smart and can handle converting all of the files to the right formats if you don't know what you're doing
